I'm not arguing any of that. I am familiar with diodes and the
solenoid's coil and with what happens when the voltage is removed. As
I said in a following post, it's a question of misunderstanding
betyween us, not an argument as to who's right or wrong. I appreciate
your input. I appreciate most of the input from the guys in this
group, even those I disagree with, and sometimes I am forced to
reassess my own position on some things. That's what learning is all
about, and all of us are still learning. Even those of us who teach
this stuff.
Thanks
Dan
